Clazy is a Clang plugin which extends the compiler with over 50 warnings related to Qt best practices ranging from unneeded memory allocations to API misuse. It’s an opensource project spawned by KDAB’s R&D efforts for better C++ tooling. At KDAB, we have a pretty cool Continuous Integration infrastructure to take care of our customers’ […]
“I have also done some last minute performance improvements with the help of KDAB Hotspot/perf, and I must say that the days of profiling with weird/huge perf command line options are gone, awesome tool!” Hotspot is a KDAB R&D project to create a standalone GUI for performance data. It is a replacement for perf report. […]
The City Lights demo is an example of Qt 3D being put to novel use to implement a deferred rendering pipeline. With OpenGL, the number of lights you can show on a screen, also affecting objects in a scene, is limited by the need to use a forward renderer. Using Qt 3D, the geometry considerations […]
At the heart of every 3D application is geometry. Qt 3D-based 3D applications are no different and require the user to either generate geometry or provide asset files for Qt 3D to load. This blog post demonstrates how Blender and its Python API could be used to write an exporter that generates geometry for Qt […]
We have released version 2.9.0 of our Qt application introspection tool GammaRay. GammaRay allows you to observe behavior and data structures of Qt code inside your program live at runtime. GammaRay 2.9 introduces a number of new features interesting to Qt Quick, QWidgets, Qt 3D and non-graphical Qt users alike. Qt Quick One focus area of […]
ERTS² expects over 400 visitors. Meet us at Booth 18! ERTS European Congress is a unique, international, cross sector event on Embedded Software and Systems, where academia, science research and industry meets.
Today I want to share 13 mistakes regarding signals, slots and connect statements and how to find them at compile time with clazy, our open-source static-analyzer for Qt. Clazy is a compiler plugin which generates warnings related to Qt. You can read more about it in our previous blog posts: How to use static analysis […]
